With the innovation and improvement of technology continuously, Chinese chemical industry is also developing. The rubber and plastic industry has gained great progress in technology and the new style roof waterproofing material has provided material base for single-layer roof covering . Hence, the single-layer roof covering with rubber and plastic will turn into law slope roof field in the future.

According to RSI magazine recent report, new style roof waterproofing material in USA has striking increase and developed leading roof material, which caused our attention. Before 1960s, the change of new style roof waterproofing technology was very small during 100years.

BUR is a new style laminated roof waterproofing material with 3 to 4 layers bitumen coating as the waterproof layer base of waterproofing material all around the world. In 1962, USA Carlisle paved EPDM new style roof waterproofing coating in Chicago O'Hare Airport roof covering, which created the first field of single-layer new style waterproofing material.

However, the development of single-layer new style waterproofing material was slow in primary stage. People are keen to choose reliable BUR chronically. The global resource’s situation in 1970s brings opportunity for single-layer waterproofing material. Firstly, Arabian oil embargo in 1973 led to the oil price boom and supply shortage of high quality new style waterproofing material and bitumen. Meanwhile, the higher energy price increased the demand of High heat resistance waterproofing material system.

It made single-layer new style waterproofing material became interesting. It can be paved in the isocyanuric acid and inflated polystyrene thermal panel. During that time，BUR also has some functional problem, such as double-layer paved fail and polyurethane thermal panel blistering ,etc.

Nevertheless, the contractors of new style waterproofing material that not included modified bitumen still used single-layer material carefully in that time. The law slope roof waterproofing material only accounted 10% market rate in 1997. Then, the quality is improved continuously and the construction technique is consummated relatively. It has increased 25% in 1984 and up to 48% in 1987. Moreover, it has added to 54% over a half , which became the leading waterproofing material.

According to the statistics, the members’ corporation of Single Ply Roofing Industry provided 27.87 billions m2 waterproofing coating in 2005, which was over two times of supply in 1984. However, the single-layer new style waterproofing material also went through a hard process. From the investigation in 1987, the contractors encountered the most problems in single-layer new style waterproofing material. When the marketing share was over 50%，several contractors reflected that the destroy and repair of single-layer products was at most and as high as 75%.
